To ILZZ 1071/0112, it may concern:

Be it known hat I, BURKARD BEER, a citizen of the German Empire,residing at Hamburg, in the State of Hamburg, Germany, have inventedcertain new and useful improvements in Devices for Projecting Life-Lines, of which the following is a descrip tion, reference being had tothe accompanying drawings and to the letters of reference markedthereon.

This invention relates to a device which is adapted for projecting orfiring life-saving lines. For this object a ring capable of engagementwith the shot is mounted in front on the gun-barrel, to which ring thelife-saving line is suspended and which is carried along with the shot.

The characteristic feature of the present invention consists in the shotbeing surrounded at those places on which the ring engages with a casingof softer metalsuch, for instance, copper or leadwhereby the shock whenthe ring is struck and carried along is diminished.

Some forms of construction of the object of the present invention willnow be explained, and these mainly embrace two groups. In the one thering is mounted on the shot when carried along with it, while in theother the shot engages over a projection of the ring, preferablyprovided with spring tongues or protuberances. In all the forms ofconstruction, however, the resting-place of the ring on the shotaccording to the present invention is made of softer material.Preferably the shot is made hollow and filled with a propellingsubstance, which imparts a more exact direction to its flight and alsomakes the same visi ble in darkness.

The object of the present invention is shown in several formsof'construction in the accompanying drawings, in Wl1ich- Figure 1 is anend view, and Fig. 2 an axial longitudinal section, of a shot and ringaccording to the first form of construction. Fig. 3 shows an elevationof the shot and a ring of altered form mounted on the barrel,

art of the barrel being shown in section. Fig. 4 is another view of thisring and shows the introduction of an intermediate member between thering and the line for better absorbing the shock. Fig. 5 is an end view,

and Fig. 6 a longitudinal section, of the shot and ring in a second formof construction. Fig. 7 is an end view, and Fig. 8 is a longitudinalsectional view, of the same.

l The shot (1 (shown in Figs. 1 and 2) is cylindrical and hollow andalso provided with l a cupola-shaped point. According to the j presentinvention the shot or projectile in i one form of construction isprovided with a casing b, of soft 111aterial-such, for instance, ascopper or lcadwhich is slightly tapering in front. The life-saving line'L is attached to ing the line 'i. This ring has a conical bore g,corresponding to the cone of the shot a, in which bore the shot a afterbeing fired enters, and in this manner carries with it the ring f andthe line i. Another shape of this ring is shown in Figs. 3 and 4, inwhich, instead of the tapering bore, it has a cylindrical bore Z. Alsoinstead of one lug h, as shown in Bigs. 1 and 2, several such may beprovided. 'lhus, for instance, in big. 4 a ring 3/ is shown with twosuch lugs Zr, and here, in addition, between the line i and the ring y aspring intermediate mcmber m is also interposed, where by the shockarising when the shot carries the ring with it is still better absorbed.

In the shots 0 and 25 (shown in Figs. 6 and 8) the ring in being carriedwith them is not mounted on the casing of the shot, but the latterengages over a corresponding projection of the ring. For this object onthe ring g in Fig. 6 a conical projection w is provided, and similarlyon the ring to (shown in Fi 8) a cylindrical projection 2, which carryabove spring hooks or protuberances r. The respective shots 0 and tareprovided with suitable conical and cylindrical recesses or turned outparts s and 1 respectively, which serve for receiving the projections,while on the ring 9 and 'w, being carried along with the shots, thehooks r are first compressed by reason of their elasticity and thenengage behind corresponding shoulders 1" on the shots 0 and t, so thattheir hold is secure. Here also the respective resting-places p and u,according to the present invention, are covered with softer metal.

Preferably all the shots are filled with a propelling substance of, thegas of which can escape during the llight through a perforation formedin the bottom.

ll aving now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, I declarethat what I claim is 1. In combination, a line-carrying ring adapted tobe carried by the muzzle of a gun,

the lug lb of a ring], which is mounted on the mouth e of the barrel andserves for conveyber, spring-fingers thereon, and a projectileprojectile having shoulders for interlocking with said fingers.

5. In combination, a line-carrying member, spring-fingers therein, aprojectile having a tapered recess for the reception of said fingers,said recess having a lining ol yieldable material.
